获取代表 C
中元组实例值的字符串
原文:https://www . geeksforgeeks . org/get-the-string-表示-tuple-1-instance-in-c-sharp/
一个元组是一个数据结构，它给你最简单的方法来表示一个数据集。您也可以通过使用字符串方法来获取表示元组对象的字符串。该方法返回一个表示元组T5】对象的字符串。此方法表示的字符串采用(Item1)的形式，这里 Item1 表示 Item1 属性值。它将代表一根弦。如果任何属性包含空值，则为空。
语法:
public override string ToString ();
返回类型:该方法的返回类型为系统。弦。因此，它将返回一个表示 Tuple < T1 >对象的字符串。
例 1:
// C# program to illustrate the
// use of ToString method
using System;
namespace exampleoftuple {
class GFG {
// Main Method
static void Main(string[] args)
{
// 1-Tuple
var v1 = Tuple.Create("Rohit");
// Get the value of Tuple<T1>
// With the help of ToString method
Console.WriteLine("Tuple 1: " + v1.ToString());
}
}
}
Output:
Tuple 1: (Rohit)
例 2:
// C# program to illustrate
// the use of ToString method
using System;
namespace exampleoftuple {
class GFG {
// Main Method
static public void Main()
{
// Nested Tuples
var T1 = Tuple.Create("Sumit", Tuple.Create("Bongo",
"Bella", "Binu"));
var T2 = Tuple.Create("Boond", "Cinki", "Chimmy",
Tuple.Create("Karan", "Micky"));
var T3 = Tuple.Create(34.9, 78.7, Tuple.Create(12.2,
34.5, 5.6, .78));
var T4 = Tuple.Create(2, 4, 6, 8, 5,
Tuple.Create(10, 20, 30, 40, 50));
// Get the value of Nested Tuples
// With the help of ToString method
Console.WriteLine("NTuple 1: {0}", T1.ToString());
Console.WriteLine("NTuple 2: {0}", T2.ToString());
Console.WriteLine("NTuple 3: {0}", T3.ToString());
Console.WriteLine("NTuple 4: {0}", T4.ToString());
}
}
}
Output:
NTuple 1: (Sumit, (Bongo, Bella, Binu))
NTuple 2: (Boond, Cinki, Chimmy, (Karan, Micky))
NTuple 3: (34.9, 78.7, (12.2, 34.5, 5.6, 0.78))
NTuple 4: (2, 4, 6, 8, 5, (10, 20, 30, 40, 50))
